Abstract
Coherence and correlations between electrons in weakly coupled quantum dots are considered in general nonequilibrium situations. The influence of strong onsite Coulomb interaction on the evolution of the density matrix of a system of coherently coupled quantum dots and on the coherence of the transport is investigated. It turns out, that spin entanglement between electrons on spatially separated quantum dots can be induced in nonequilibrium. We study in detail the precursors of this phenomenon.
